幕墻一貫反應用于我國各地公路舉措措施建設當中。金屬波紋管涵投入到了青海公路施工當中，三年的實踐證實，鋼波紋管在北方(fang)嚴寒地區完全符合公路建設當(dang)中(zhong)的涵(han)洞施(shi)工要求。  

鋼波紋管在嚴寒地區完全符合施工要求

跟著波(bo)紋管涵(han)在世界各地(di)的安裝(zhuang)使(shi)用(yong)，證實(shi)了此(ci)種(zhong)結(jie)構(gou)在各種(zhong)使(shi)用(yong)情況下的通用(yong)性。在我(wo)國改革(ge)開放后，深圳及大同煤(mei)礦(kuang)開始從(cong)國外(wai)入口(kou)成品(pin)波(bo)紋管涵(han)進(jin)行(xing)涵(han)洞施工。之后，上海(hai)市公路治理處、上海(hai)市政工程設計研究院、上海(hai)同濟大學對金屬(shu)波(bo)紋管涵(han)進(jin)行(xing)了動、靜載(zai)試驗，結(jie)果表明能(neng)知足設計使(shi)用(yong)要求，填補了海(hai)內的空缺，且(qie)迅(xun)速(su)得到(dao)推廣應用(yong)。

公路(lu)工(gong)(gong)程的(de)涵(han)(han)洞(dong)一般(ban)采(cai)用金屬(shu)(shu)筋混(hun)(hun)(hun)凝土制作。現采(cai)用金屬(shu)(shu)波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)代替金屬(shu)(shu)筋混(hun)(hun)(hun)凝土進行(xing)涵(han)(han)洞(dong)施(shi)工(gong)(gong)在海內時一項新(xin)技(ji)術(shu)，金屬(shu)(shu)波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)以其機能不亂、安(an)裝利便、有(you)利環保、造(zao)價低(di)等(deng)長處迅速(su)在公路(lu)施(shi)工(gong)(gong)中代替了(le)(le)金屬(shu)(shu)筋混(hun)(hun)(hun)凝土施(shi)工(gong)(gong)的(de)涵(han)(han)洞(dong)，發展遠(yuan)景(jing)非常廣闊(kuo)。在公路(lu)施(shi)工(gong)(gong)中，應用金屬(shu)(shu)波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)代替金屬(shu)(shu)筋混(hun)(hun)(hun)凝土進行(xing)涵(han)(han)洞(dong)施(shi)工(gong)(gong)的(de)歷史已經有(you)100多年了(le)(le)。1896年，美(mei)國(guo)率(lv)提高(gao)前(qian)輩行(xing)波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)通道、涵(han)(han)管(guan)(guan)的(de)可行(xing)性研究(jiu)。其后，在美(mei)國(guo)、加拿(na)大(da)(da)、澳(ao)大(da)(da)利亞等(deng)國(guo)的(de)公路(lu)建設(she)中，均采(cai)用了(le)(le)金屬(shu)(shu)波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)進行(xing)涵(han)(han)洞(dong)的(de)施(shi)工(gong)(gong)。1990年，日本高(gao)速(su)公路(lu)設(she)計(ji)，規范制定了(le)(le)波(bo)紋(wen)(wen)(wen)(wen)管(guan)(guan)涵(han)(han)設(she)計(ji)技(ji)術(shu)規范。  

金(jin)(jin)屬(shu)(shu)(shu)波紋管涵(han)(han)是(shi)將薄金(jin)(jin)屬(shu)(shu)(shu)板(ban)板(ban)面(mian)壓成(cheng)波紋后，卷制成(cheng)管節(jie)，可以增加管節(jie)的(de)剛度(du)和(he)對(dui)管軸壓力的(de)抵擋強度(du)；出廠前采用熱(re)浸(jin)鍍(du)鋅(xin)工(gong)(gong)(gong)(gong)藝和(he)施(shi)(shi)工(gong)(gong)(gong)(gong)現場噴涂瀝青，雙(shuang)層防腐處理保(bao)證(zheng)了(le)使用壽命；用此種(zhong)管節(jie)修(xiu)建的(de)涵(han)(han)洞(dong)(dong)被稱(cheng)為波紋金(jin)(jin)屬(shu)(shu)(shu)管涵(han)(han)。實踐(jian)證(zheng)實，用金(jin)(jin)屬(shu)(shu)(shu)波紋管涵(han)(han)代替(ti)金(jin)(jin)屬(shu)(shu)(shu)筋(jin)混(hun)凝土進行涵(han)(han)洞(dong)(dong)施(shi)(shi)工(gong)(gong)(gong)(gong)，不(bu)管從施(shi)(shi)工(gong)(gong)(gong)(gong)周期、施(shi)(shi)工(gong)(gong)(gong)(gong)造價、環(huan)保(bao)意義等方面(mian)都(dou)有(you)其(qi)不(bu)可相比的(de)優勝性，且(qie)用金(jin)(jin)屬(shu)(shu)(shu)波紋管涵(han)(han)進行涵(han)(han)洞(dong)(dong)施(shi)(shi)工(gong)(gong)(gong)(gong)，可大大進步道(dao)路行車的(de)恬靜度(du)與安全性，避免(mian)道(dao)路中(zhong)涵(han)(han)洞(dong)(dong)的(de)“錯臺跳車”現形，有(you)利于解決西北地區嚴(yan)寒霜凍對(dui)砼(tong)管涵(han)(han)結(jie)構的(de)破壞題目。

波(bo)(bo)紋(wen)(wen)管(guan)設計(ji)計(ji)算的參數為剛(gang)(gang)度(du)、應(ying)力(li)、有(you)效面積、失穩、答應(ying)位(wei)移、耐壓力(li)和使用壽命。波(bo)(bo)紋(wen)(wen)管(guan)的剛(gang)(gang)度(du)計(ji)算，波(bo)(bo)紋(wen)(wen)管(guan)的剛(gang)(gang)度(du)按照載荷及位(wei)移性質不同，分(fen)為軸向(xiang)剛(gang)(gang)度(du)、彎曲剛(gang)(gang)度(du)、扭轉(zhuan)剛(gang)(gang)度(du)等。目前在(zai)波(bo)(bo)紋(wen)(wen)管(guan)的應(ying)用中，絕大多數的受力(li)情況是軸向(xiang)載荷，位(wei)移方式為線位(wei)移。

根據鋼波紋管的結構(gou)特點，可以把(ba)波(bo)紋管當作圓環殼、扁(bian)錐殼或圓環板(ban)所組成。設計計算(suan)波(bo)紋管也就(jiu)是(shi)設計計算(suan)圓外殼、扁(bian)錐殼或團環板(ban)。

金屬波(bo)(bo)紋(wen)管(guan)設(she)計(ji)的(de)(de)(de)理論基礎(chu)是板殼理論、材料力學、計(ji)算(suan)(suan)數學等。波(bo)(bo)紋(wen)管(guan)設(she)計(ji)的(de)(de)(de)參(can)數較多，因為(wei)波(bo)(bo)紋(wen)管(guan)在(zai)系統(tong)中的(de)(de)(de)用途不(bu)同，其(qi)設(she)計(ji)計(ji)算(suan)(suan)的(de)(de)(de)重點(dian)也不(bu)一樣。例如，波(bo)(bo)紋(wen)管(guan)用于力平衡元(yuan)件(jian)(jian)，要(yao)求(qiu)波(bo)(bo)紋(wen)管(guan)在(zai)工(gong)作(zuo)(zuo)范圍內(nei)其(qi)有(you)效面積不(bu)變或變化(hua)很小，用于丈量(liang)元(yuan)件(jian)(jian)，要(yao)求(qiu)波(bo)(bo)紋(wen)管(guan)的(de)(de)(de)彈性(xing)特性(xing)是線性(xing)的(de)(de)(de)；用于真空(kong)開(kai)關管(guan)作(zuo)(zuo)真空(kong)密(mi)封(feng)(feng)件(jian)(jian)，要(yao)求(qiu)波(bo)(bo)紋(wen)管(guan)的(de)(de)(de)真空(kong)密(mi)封(feng)(feng)性(xing)、軸向(xiang)位(wei)移量(liang)和疲憊(bei)(bei)壽命；用于閥(fa)門(men)作(zuo)(zuo)密(mi)封(feng)(feng)件(jian)(jian)，要(yao)求(qiu)波(bo)(bo)紋(wen)管(guan)應具有(you)一定(ding)的(de)(de)(de)耐壓力、耐侵蝕、耐溫度、工(gong)作(zuo)(zuo)位(wei)移和疲憊(bei)(bei)壽命。
